The board of Horse Racing Ireland has approved a number of amendments to racing's Covid-19 protocols, all of which are consistent with Government guidelines.
The changes will come into effect from Wednesday.
The prohibition on attendance of those aged over 70 in the various attendee categories which are permitted under the protocols, such as trainers, stewards and vets, will be removed.
The current limit of no more than three journalists and three photographers will be increased to a maximum of five.
One representative of associations whose attendees are permitted to be at race meetings will be allowed.
Premier Handicaps in Ireland will be opened to international runners, in addition to all Listed, Group and Grade races under both codes.
The current health screening and temperature checking arrangements will continue for all attendees.
From Monday 20 July, other amendments have been approved.
Two owners per horse will be permitted to attend for their race only, subject to pre-health screening and temperature checks on arrival.
Racecourses will be allowed to nominate up to five attendees, which could include sponsors, racecourse board and committee members, and social-distanced trophy presentation for the feature race will be permitted.
In line with current Government guidelines, masks will continue to be mandatory for those working indoors or when unable to socially distance at all times.
Saunas or showers will remain closed, with an expanded weighing room space continuing to be provided, and this will see a continuation of the current 2lb increase in weights across the board under both codes.
To facilitate the current health pre-screening system, 48-hour declarations will continue to operate.
Safety limits will remain at a general maximum of 18 per race or less as required for social distancing and stable capacity reasons, with the exception of key high-value feature races.
There will be a maximum of 20 for Premier Handicaps at the Curragh and normal limits retained for the feature handicaps at Galway, including 20 for the Hurdle and 22 for the Plate.
Chief Executive of HRI Brian Kavanagh said: "Since we resumed racing in Ireland on 8 June, the level of care and compliance with the Covid-19 protocols has been excellent and is appreciated by the Covid-19 teams in Horse Racing Ireland and the IHRB.
"While we’re announcing some easing of the restrictions today, it is very important that everybody continues to comply with the rules on the racecourse around social distancing and face masks, and the requirements around pre-health screening.
"We are delighted to be able to confirm today that owners will be permitted to return to the racecourse on July 20, with certain restrictions.
Owners play a key role in Irish racing and their loyalty during this difficult period has been especially noteworthy."
